How is the image in a mirror created? Are there infinitely many light rays?
My motivation for the question is from image processing. We work with images as discrete 2D functions, as matrices. Spatial sampling is done, and also quantization. Then I thought, well that is far from perfect, I wonder how does God create images? And then I thought of a real example, well, the mirror! The 3D world is projected on a 2D plane, the mirror. So how many rays arrive on the mirror? Infinitely many? Does God do spatial sampling or is the image in the mirror continuous?
